Encoding hybrid automatic repeat request acknowledgements in a multi-antenna wireless communications system

摘要

There is provided a method performed by a User Equipment, UE, for encoding Hybrid Automatic Repeat Request, HARQ, Acknowledgements, ACK/NACK, in a multi-antenna wireless communications system. The method comprises the step (S1) of bundling, also referred to as co-representing, a HARQ-ACK/NACK to be sent in response for a transport block of information with a HARQ-ACK/NACK to be sent in response for another transport block of information, when more than two transport blocks of information are used. The method also comprises the step (S2) of encoding the bundled HARQ-ACK/NACK information.
